When the Hegemony Armed Forces began to introduce the new Avatar-class heavy cruiser to service the decision was made to place the bulk of the older Aegis-class heavy cruisers in mothballs, orbiting the sun at a position somewhere between Terra and Mars, with a small number staying in active service as training vessels. The ship which would later be known as the Eagle Eye was one of the Aegis-class ships to have survived her service to the Terran Hegemony, and when First Lord Ian Cameron of the Star League chose to bring the Aegis fleet out of mothballs in 2582 two-thirds of the Aegis class went on to service in the newly-formed Star League Defense Force; the remaining third of the fleet - some 30 to 36 vessels in all - were sold to the various Star League member states, and the Eagle Eye was purchased by the Federated Suns along with a small number of sister ships.
The FSS Eagle Eye went on to serve with the Federated Suns Navy for centuries; in 2765 she was one of six Aegis-class WarShips still in active service with the FSN and was the lead ship of the FSN's Spinward Fleet, operating in the Draconis March region of the Federated Suns. The Eagle Eye was the flagship of Admiral Aristotle Buchwald, who had command of a fleet consisting of a second Aegis, a New Syrtis-class carrier, two Robinson II-class transports, four Davion II-class destroyers, a Congress-D-class frigate and a Vincent Mk. 39-class corvette.
